12x - 56 = y. Hope it helps! :) If you could vote my answer as the brainiest, that would be awesome! :)
5.B
what is 6
7. It’s equal, should be c
Answer:
.
Step-by-step explanation:
We want to convert the function into the form that let's us easily find the x-intercept, and it would be for the form
because then we can find the x-intercept in the following manner:



We factor our function
and get

Now this form let's us easily find the x-intercepts:


and so we pick the second choice: f(x)=(2x+1)(2x-1).
Answer:
see in the graph, the circle has: the centre I(3; -2)
r = 3
=> the equation: (x - 3)² + (y + 2)² = 9
The answer is 17. 30-13=17.
